I started getting these clear little bubbles under my skin on the sides of my fingers and feet around age 10 or 11. The area would itch like crazy and scratching would break the "bubbles" which were really blisters i think, releasing this clear fluid and revealing the bottom layer of skin. Still the itching would continue, and I've never been able to resist an intense itch so I'd end up scratching off whole large areas of my skin where the blisters would be. And I'd be so grossed out not only by the appearance of the blisters but the skin underneath them, all red and sometimes pitted, like the blisters left an indent on the underlying layer of skin. This red area would become extremely painful if it came in contact with anything at all and I'd usually have it all covered in bandages. Then the skin around the edges of the wound starts to dry up, and once all the itchy skin is either scratched off or dried up dead and white, the raw red skin will start to heal over itself rather quickly. The whole cycle would take a week or two, from first appearance of the blisters to the healing skin. I did have many outbreaks that were consistant for several months in my teens, but for the most part the blister flares would be isolated and pop up every month or two.
So, having this crazy skin condition that I'd never heard of or seen anyone else dealing with, I talked to my Mom, who also suffers with skin conditions but nothing like what I had, and she took me to dermatologists to check it out. My Mom jokingly referred to my skin outbreaks as the "creeping crud" which I thought was funny. Anyway the dermatologists, I ended up seeing about 5 different ones throughout my teens for a couple of different things, would always diagnose my skin problem as basic eczema and prescribe some cream that didn't do much to help.
As I got older the outbreaks got rarer and less severe, but it would still happen to the point where I needed to do something about it. So after another failed trip to see a different dermatologist I started doing some online research on skin disorders on my own, determined to find a description that matched with my own experience. about seven years ago I finally found what I was looking for: dyshidrosis. The pictures and descriptions all matched perfectly, and I was one hundred percent certain that's what I had. I was shocked that I was able to diagnose myself when several dermatologists couldn't. But apparently dyshidrosis is pretty rare. I later had this confirmed by a new dermatologist, about 5 years ago, when I went to get a wart removed from my hand and happened to also be at the start of a flare up. He gave me another near useless cream but also gave me some advice on how to prevent the flare ups. One thing he said helps some people during an outbreak is to make a paste of baking soda and water, smear it all over the blisters and leave it there for about 20 minutes, then rinse it off with just water and dry the skin well, and this should help with the itching and also dry them out. I have not, however, found a treatment that helps entirely get rid of the blisters once they've appeared, or prevents them from progressing into the mess they inevitably become.
I can happily say that now in my 20s I very rarely get a flare up of dyshidrosis and when I do it's very minor in comparison to what I experienced when I was younger. Thinking now, it's actually been over a year since I last noticed any blisters on my fingers or feet. Hopefully this trend continues but if it does get bad again I'm saving this post to try the anti-histamine treatment.
Sorry my comment was so long, I've never actually met or chatted with someone who deals with dyshidrosis so I got a little excited and wanted to share my story, even though I'm very "late to the party" at this point.
TL;DR: I have dyshidrosis, although not as bad as I used to, and nothing really helped with the flare ups until I tried baking soda + water on the skin for 20 minutes then rinsed off with just water. Rarely have flare ups now but if it gets bad again I'll try the anti-histamine treatment.
